Hi mates,
Need your help with my PSU, Here's my configuration:-
PSU: Gigabyte Superb E620
Intel i5 3550 Ivy Bridge
Gigabyte ga-b75m-d3h MoBo
4 gb GSkills 1600mhz Ram (1module)
500 GB SATA II hdd samsung 7200 rpm
60 GB Kingston SATA III SSD
DVD-RW SAMSUNG
other: 3 usb devices, 3 Case fans
windows 7 64 bit
PSU specification:
AC INPUT 100-240Vac 7.5-4A
FREQUENCY 50-60Hz
PFC TYPE Active PFC
DC OUTPUT +3.3V +5V +12V1 +12V2 -12V +5Vsb
OUTPUT CURRENT 24A 24A 18A 18A 0.5A 2.5A
Peak output 620w, 500w continous output (total 36A on +12v rail) (80+ certified)
I have bought a Radeon 7850 2 gb ddr5
I found that its Max power consumption is 130w (11Amps approx. on 12v rail)
PSU's
12V2 has (4+4pin) 12V CPU Connector and 1 (6+2)-pin PCI-E Connector
12V1 has all the other pins + the other (6+2)-pin PCI-E Connector
Now guys I'm skeptical whether I should connect 12V1 or 12V2 (6+2)-pin PCI-E connector to the 7850,
as 12V2 is already used by CPU (max consumption of i5 3550 126w (around 10.5 amps)
while on the other hand +12V1 will be already powering the graphics card though PCIE port+ it is running all the other components.
please let me know though which (6+2)-pin PCI-E connector I can achieve the best power efficiency without touching the limits of either rail.
I cannot return this PSU and I haven't installed my card either.....
Help me so that I can install the card soon....
Thanks in advance
